Joe Douthwright, a London, Ontario native, embarked on a journey after completing his undergrad at Wilfrid Laurier University in the late '90s. An opportunity to work in Japan for 1 year ended up spanning over 12 years.

It was during these years that he got inspired by the burgeoning solar PV industry in Japan and its traction in Ontario. Joe pursued further studies in Japanese, completed his MBA while training in solar PV technology. 

When he moved back to settle in Niagara Region it became clear that there was demand to facilitate business owners and homeowners efforts to be more efficient, cut consumption and produce solar power for their homes, farms, and businesses.

Now and with over a decade of hands-on project experience in solar PV installations, energy-efficient LED lighting retrofits, EV charging, and battery storage systems, DES is just getting started. 

We're proud to have earned the confidence and trust of our industry partners, suppliers, contractors, and clients across diverse sectors in Ontario.
